c 1 A CSQL i an .L H 8 plate, and around the thread-guide socket Themarginal flange 20 around the threadguide-socket is preferably notchedor split in a number of places, and may be given. a tapered or conicalform, as most clearly illustrated in Figs. 5 and 6. Secured in thethread-guide support as thus constructed is a porcelain thread-guide 21,which prefer-- ably has a circlnnferential groove 22 and a bottom.flange The grooved portion 232 of the porcelain guide 21 is preferablyof a truncated form, the diameter of the bottom flange 23 beingpreferably substantially equal to the diameter oi the body portion ofthe porcelain guide immediately under the top flange thereof, and Iregard this as an especially desirable form of construction, as I havefound in practice, that by forcing a threadguide of this form into itssocket, as illustrated in Figs. 5 and 6, the thread-guide will beclamped and held in a rigid firm manner. It is obvious, however, thatthe body portion of the thread-guide need not necessarily be of taperingor truncated form, as herein shown.

To adjustably secure the thread-guide supporting-plate 1'? to thefinger-head, the plate 17 extends loosely through the front flange 14:of the finger-head, and is adjustably clamped in position, so that whenthe same has been moved in or out, or swung sideways to the desiredposition, it may then be solidly clamped or fastened. The clampingmechanism preferably employed coinprises a blank-headed screw 24: whichextends through clamping-plates 25, and through a slot 27 in the plate17, with a nut 28 threaded on to the lower end of the screw 24.

I am aware that numerous changes may be made in practicing my inventionby those who are skilled in the art, without departing from the scopethereof as expressed in the claims. I do not Wish, therefore, to belimited to the construction I have herein shown and described, but

"What I do claim and desire to secure by Letters Patent of the UnitedStates is In a construction of the class described, the combination of athread-guide of porcelain having top and bottom flanges forming betweenthem a circumferential groove, and

a fiat sheet metal plate constituting a holder having a spring-flangeadapted to spring into engagement with the groove of the thread-guidebetween the flanges when the same is forced into place therein, wherebythe thread-guide will be frictionally held from turning and displacementby the walls of said spring flange and will project both above and belowthe sheet metal holder.

In testimony whereof I havehereunto set my hand, in the presence of twosubscribing witnesses LEWIS, T, HOUG-HTUN.
